Application filed May 19, 1916.

T 0 all 1li/tom t may concern Be it known that I, DAVID lV. GARNER, acitizen of the United States, residing at Grme, in the county of Marionand State of Tennessee, have invented new and useful Improvements inLocks, of which the following is a specification.

This invention relates to a loclr especially adapted for securing haspsto staples.

he primary object of the invention is to provide a lock for the purposedescribed which may be advantageously used upon mail bags, although itis so constructed as to enable the lock to be used in connection withthe hasp and staple upon barn doors if found desirable. v

Another object of the invention is to provide the lock with a springcontrolled bolt which when moved to an unlocked position by means of akey for this purpose may be held in such position by a spring lingercarried by the casing and engageable theren with.

A further object of the invention is to so arrange the spring fingerwithin the casing that when the bow of the staple is inserted within thecasing, the spring linger will be released from engagement with the boltand allow the spring which controls the same to move the bolt to lockedposition.

A still further object of the invention is to provide the bolt with aspring pressed tumbler connected with a spring controlled detent mountedto slide in the bolt and adapted to engage with a guide rib in thecasing when the bolt is in locked position to prevent said bolt frombeing retracted by means other than a key designed for this purpose.

With these and other objects in view, the invention resides in the novelcombination and arrangement of parts which will be hereinafter describedand particularly pointed out in the claims.

The preferred embodiment of the invention has been illustrated in theaccompanying drawing, although no restriction is necessarily made to theprecise details of construction therein shown, as changes, alterations,and modifications within the scope of the claims may be resorted to whendesired.

Like characters of reference denote correspending parts throughout theseveral views in the drawing, in which:

strueted in accordance with the invention and showing the same connectedwith a staple to loclr a hasp thereto. Fig. 2 is a view similar to Fig.1 showing the casing of the lock broken away. Fig. 3 is a plan view ofthe reversed side of the lock showing the casing broken away. Fig. l isa View similar to Fig. 3 and showing the bolt in retracted position.Fig. 5 is a vertical longitudinal sectional view on the line 5 5 of Fig.el showing the Vbolt held in a retracted 'position by means of thespring finger on the casing. Fig. G is a detail perspective view of thelocking bolt removed from the casing. Fig. 7 is a detail perspectiveview of the tumbler operated detent, and Fig. 8 is a side elevation ofthe lrey for retracting the loclring bolt and operating the springcontrolled tumbler.

Referring now to the drawing in detail, the numeral 1 designates thelock casing which is substantially rectangular in shape and comprises abottom 2, end walls 3 and 4i, sides 5, and a cover plate (3. The coverplate 6 has formed therein between its ends a keyhole 7 and is securedto the sides and end walls of the casing in any suitable manner. Thebottom 2 of the casing has formed therein an elongated and transverselyextending opening 8 adjacent the end 3 of the casing and adapted to havepassed therethrough the body of the staple indicated in Fig. 1 of thedrawing by the numeral 9. The end wall 3 of the casing has formedtherein a vertically extending recess 10 IOpening out interiorly of thecasingabove the opening S in the bottom thereof. Partitions 11 and 12extend transversely of the casing interiorly thereof and are spaced fromeach other and from the end walls of the casing, said partitions beingrecessed between their ends, as at 13, with the recesses alining witheach other to form a guide way for a locking bolt 14 which thepartitions support for sliding movement within the casing. A key stud 15extends laterally from the inner face of the bottom 2 between thepartitions 11 and 12 and is arranged adjacent a ward 1G also extendinglaterally from the bottom 2. which extends longitudinally 0f the casingis provided at one end with a head 17 adapted to be received in therecess 10 when the bolt is in locked position and has formed thereon atits other end an extension 18 arranged below the partition 11 andinserted The locking bolt 1&1

within a coiled expansion spring 19 having an end bearing against theend wall 4 0f the casing.

From the above described arrangement of they locking bolt within thecasing, it will, of course, be understood that the spring 19 normallyexerts tension on the bolt to move the head thereof above the partition12 and into the recess 10.

The locking bolt 14 is recessed upon one side, as at 20, between thehead 17 and extension v18 to form a shoulder 21 with which a bit 22 on akey 23 shown in Fig. S in the drawing is adapted to contact and movethelocking bolt to retracted position against the influence of the spring19. The locking bolt 1 14 is recessed for the greater portion of itslength upon one side, as at 24, between the head17 and extension 18 Vtoform a shoulder 25, the bottom wall 26 0f said recess beingVtransversely, channeled, as at 27, adjacent the shoulder 25.

A leaf spring 28 extends longitudinally of the recess 24 and has one endsecured in a kerf upon the head 17 the other end of said spring beingadapted to bear against a tumbler 29 pivotally connected with the bottomwall 26 Vof the recess 24, said tumbler having formed thereon at itsfree end a detent operating finger 30.

' A detent 31 is arranged within the recess 24 and has its bottom faceadapted to contact with the shoulder 25 and has formed in its upper facea recess 32 in which is received the operating finger 30 on the tumbler29. The detent 3l is further provided upon one side with a rib 33arranged in the transversely extending channel in the bottom of saidrecess whereby said detent may be supported by the shoulder 25 andguidedV transversely of the recess by the channel and rib 33 when thetumbler 29 is turned about its pivotal connection with the locking dogby the bit on the key 23.

One end of the detent 31 is normally held projected beyond the recessedside edge of the locking dog 17 by means of the tumbler 29 and spring 28to engage with the partition 11 when the locking bolt is in lockedposition, said projecting end being rounded, as at 34, and contactingwith one end of a leaf spring 35 carried by the upper face 36 of thetumbler 29 and which is arranged in the path of movement of the bit ofthe key, the spring 35 serving to hold the detent from being projectedfrom within the recess 24 when the locking bolt is moved to lockedposition.

A spring lingerV 37 is secured to the cover plate 6 within the casingand arranged in the path of movement of the bow of the staple whenpassed through the opening 8 in the casing, the free end of said fingerbeing received in a recess 38 inthe head 17 of the locking bolt whensaid bolt is in locked position and adapted to contact with an end onthe head 17 when the bolt has been retracted by means of the key 23 andto hold said bolt in retracted position against the iniiuence of thespring 19.

'It will, of course, be understood that as the bow of the staple ispassed through the opening 3 when the locking bolt is held in retractedposition by the spring finger 37, the said finger will be disengagedfrom the end of the locking bolt to allow the spring 19 to move the boltto a position between the arms of the staple in which an end on the headwill be received in the recess 10 in the end wall 3 of the casing.

When it is desired to remove the lock from the staple as shown in Fig. 1in the drawing, the key 23 is inserted through the key-hole in the coverplate 6 and engaged with the key stud 15. The key is now turned to causethe bit thereon to depress the free end of the tumbler 29, such movementimparting sliding movement to the detent 31 to remove its projecting endfrom contact with the partition 11. Further turning movement of the keywill cause the bit thereon to engage with the shoulder 21 and slide thebolt to a position within the casing in which the upper end of the head17 is below the bottom edge of the opening S, at which time the end ofthe spring finger contacts with the end on the head and holds the boltfrom'upward movement and assists in ejecting the staple from within saidopening. The key may now be withdrawn from the casing and when it isdesired to again apply the lock to the staple, the bow of the staple ispositioned within the casing through the opening S. As the bow of thestaple is brought into contact with the spring finger 37, the same isreleased from the end of the head 17 allowing the spring 19 to move thelocking bolt upwardly until an end on the head is received in the recess10, at which time, the head will be between the arms of the staple andthe curved end of the detent 31 projected beyond the recessed side edgeof the locking bolt and in contact with the partition 11, thuspreventing the locking bolt from being retracted by other means than thekey 23.

From the foregoing description, taken in connection with theaccompanying drawing, it is at once apparent that a lock has beenprovided for securing a hasp to a staple which is inexpensive ofmanufacture, yet highly efficient in use.

Having thus described the invention, what is claimed as new, is:

1. A device of the class described comprising a casing having a slottherein to rcceive the bow of a staple, a key operated bolt arrangedwithin the casing and having an end to be received between the arms ofthe staple when the bolt is in locked posi- CIK tion7 a key operatedtumbler carried by the bolt, and a detent mounted to slide on the boltand arranged in the path of movement of the tumbler.

2. A device of the class described comprising a easing having a slottherein to receive the bow of a staple, a key operated bolt Within thecasing having a shoulder eX- tending transversely thereof, a detentarranged upon the shoulder and movable transversely of said bolt7 a keyoperated and spring controlled tumbler Carried by the bolt andoperatively engaged with the detent to hold one end thereof extendedbeyond the bolt when the same is in looked position, and a member on thetumbler contaeting with the detent adapted to limit the sliding movementof the detent in one direction under the iniiuenoe of the tumbler.

3. A device ofthe class described oomprising a casing having a slottherein to receive the bow of a staple, partitions within said easing, akey operated locking bolt mounted for sliding movement within saidpartitions and having an end adapted to extend beyond said slot whensaid looking `bolt is in looked position, a key operated and springcontrolled tumbler carried by the bolt, 'and a detent mounted to slidein the bolt and operatively connected with the tumbler whereby saiddetent may be held in Contact with one of said partitions when thelocking bolt is in locked position.

In testimony whereof I affix my signature.
